Bai Yueyu hopes to explore figurative emotions and expressions through seemingly abstract structures. It feels related to reality through the folded space, yet it is flat, expressing a sense of artificial and imaginary space. By the folding structure, the lacquer is given a subtle but rich, psychedelic, refractive texture. The picture is in a dark tone, with much black appearing. The natural blackness of lacquer moves Bai Yueyu's mind and educates him to observe it and follow lacquer's "slow rhythm". The warm brown color of the raw lacquer dries and cures to such a rich black color on the dark base: loose yet tight, cold yet warm, subtle yet textured. The combination of colors and tones in the picture enters the black hole of space and material and suddenly becomes bright and rich in the artist's heart. Bai Yueyu sees the enriched colors in the darkness, the erratic colors, and yet the essence of the lacquer. This essence points to space itself: emptiness, vagueness, and pervasiveness. While perceiving this material and this space, the artist also enters it, bound by it and wandering in it. It makes him believe that the material, lacquer, itself is spatial and that the space itself is indeterminate.
There is a real sense of existence in "The Folded Space", but it is not the actual space, rather a moment in the past and an echo of this moment. Through the subjective, intoxicating act of contemplation, space is led to its purity, becoming an absolute, flat, impressionistic existence detached from its original functionality and value. The space becomes neutral; it can hold everything and be held by everything.
